Tonga Room's indoor rain joke

The Tonga Room & Hurricane Bar occupies a ballroom inside the Fairmont Hotel and is famous for a periodically activated indoor rainstorm and a central floating band stage. The bar's simulated rain feature and tropical decor have been a noted novelty since the room's mid-20th-century conversion to a tiki venue. Locals and visitors commonly joke that it is one of the few places in San Francisco where it literally 'rains' indoors. The Tonga Room is located in a prominent Nob Hill hotel and is frequently cited in guides to the city's kitschy landmarks.
